ABSTRACT:

C-73-1-101 iron ammonia synthesis catalyst from United Catalyst, Inc., was reduced in the laboratory with H sub 2 at 450 degrees C, 6000 hr exp -1 GHSV for 48 hours. The reduced catalyst has been examined with Scanning Transmission Electron Microscope (STEM). Large iron crystallites, >100A, and a broad size distribution have been confirmed. Only metallic iron was detected in the x-ray diffraction analysis. The reduced C-73-1-101 catalyst has been tested in the Fischer-Tropsch fixed-bed catalyst testing plant under four sets of reference conditions (Runs 3, 6, 7, 8).  Preliminary analyses of these tests are described in this report. The presence of two independent parallel product recovery systems allowed separating the products collected initially during the line-out from those collected at the desired conversion level and also allowed multiple material balance periods in an extended run. The products recovered during the run and the wax retained on the catalyst were later analyzed by gas chromatography mostly to determine the carbon numbers. Relatively small amounts of catalyst diluted with alpha -Al sub 2 O sub 3 powder were used to prevent excessive temperature increases. Total material recoveries, after correction by the amount of recovered argon, were 96-99% in all runs except in Run 8. The Anderson-Schulz-Flory plots, for the products recovered during the course of the runs, were mostly linear but indicate the possibility of further improvements in the product recovery and analysis techniques. Various ruthenium salts have been preliminarily evaluated for preparing catalysts by applying a micelle technique, and some promising salts were identified. TGA analysis performed on a micelle-derived catalyst supported on alumina indicates that 400 degrees C may be a suitable calcination temperature. 36 figures. (ERA citation 10:018081)
